The GOOD VS. EVIL FURBLETS 2 PACK includes May-May and Greenie-Meanie, two mini Furby friends with contrasting personalities. Both respond to touch with over 45 sound effects each, playing music inspired by their individual traits and communicating in Furbish (no human language support). Each toy comes with three A76/LR44 button cell batteries pre-installed. Interaction occurs in three ways: pressing the beak triggers feeding sounds, tapping the heart gem activates music, and pressing the top of the head powers the toy on/off while playing playful babbling sounds. The 2-inch (5 cm) plush toys feature removable keychain clips for attaching to backpacks or bags and should only be surface cleaned. A peekaboo function allows the ears to fold down and pop back up when the head is pressed. When two Furblets are held together with their mouths pressed simultaneously, they harmonize in a duet. The toys are also compatible with the latest Furby (sold separately)—activating Furdar mode lets Furby react to its "dee noo-lahs" (little friends).
